HAT-SWEAT-SEWIN G MACHINE.

T all 107102;: it may concern:

Be it known that we, WILLIAM A. Kmcirr and LEO BAUER,.each a citizen ofthe United States, and each resid ng in the city of New ark, county ofEssex, and State of New Jersey, have ointly invented a certain new anduseful Improvement in Hat-Sweat-Sewmg Machines, of which the followingis a speci being sewed in place, to make use of a corrugated wheel,which contacts with the outer surface of the hat and usually bearsagainst the band or ribbon or other trimming material which is appliedto the hat to afford a finish at the lower portion of the crown adjacentto the rim.- The application'of the feeding means in this neighborhoodfreq-uently results in marking the ribbon or the upper surface of therim in an objectionable manner and it is not uncommon for the ribbon tobe torn and the hat ruined by the feed being so applied. With a sewingmachine constructed in accordance with our invention this objectionablefeature is not present, as the feedis applied, not to the outer surfaceof the crown or to the uppe surface of the rim, but it is applied on thelower surface of the hat rim next to the.

edge of the sweat band and, while a machine constructed in accordancewith ourinvention is not likely to leave feed marks on the hat, if itshould happen that the hat is marked in sewing the sweat band therein,

the marks will not be noticeable, as such marks as appear will be on theunder surface of the rim next to the edge of the sweat band where theywill not be likely to be observed.

Another feature of ourv invention resides in making provision forholding the hat firmly and securely in place while the sweat band isbeing sewed therein. Sewing a sweat band in a hat is a delicateoperation,

as it must be blind sewed and the Stitches must not penetrate throughthe material of the hat seas to be visible from abo e, and

at the same time the stitches must penetrate siiiliciently to secure thesweat band firmly in place so it will not come loose or be readilydetached. According to our invention the same means which is made use offor feeding the hat and which, as already stated, is applied to theunder surface of the rim near the sweat band, also serves as a means forpressing and holding it firmly in place during the sewing operation.

Another feature of our invention consists in the provision of a movablesupport for the hat during the sewing operation, this support being freeto move with the hat, instead of being fixed, so that it is notnecessary as heretofore to move the-hat along over a fixed and immovablesupport and this results in it being possible to perform the feedingoperation more easily and to lessen the necessary force and pressureused for feeding, thereby decreasing the liability of damage to the hatfrom pressure; applied in ance with customary usage we make use ofachain stitch for sewing the sweat band in The edge ofthe sweat leatherand a portion of the under surface of the hat rim adjacent thereto,where the hat is bent over to form the junction between-the crown andrim, are whipped together, the needle passing partially through thematerial of the hat at the bend and,through the edge of the sweatleather and the thread being drawn back in a loopover the exposed edges,through which loop the needle passes on its next forward movement, toform the chain stitch. A cord is preferably sewed in between the edge ofthe sweat band and the material of the hat. although this may beomitted, of course, if desired. A looper is made use of for drawing aloop in the thread after the needle has passed through the parts to hesewed together and. as the thread has to be drawn out into a fairly longloop in order to provide sufficient length of thread for the whippingoperation, a considerable pull is exerted by the thread when the loop isformed and this, according to the present practice, frequently resultsin tearing the soft material of the sweat leather, and if the tension011 the thread is sufficiently loosened to prevent this effect he ingproduced, the thread is likely to become snarled and stop the machine orspoil the hat. In order to take care of this situation, we have providedpositive mechanical means for drawingolf from the spool a suflicientlength of thread for forming the loop and for. releasing the tensionupon this extra length of thread as it is needed for making the loop andalso for drawing up-the thread after the loop is formed and the needlehas passed through it to form the next stitch, so that, While suflicientlength of thread will ahvays be available for forming the loopwithouttearing the sweat'band or other parts being sewed, the thread after theloop has been formed and the next stitch produced will be dnawn up so.as to make the stitching of the proper snugness;

Other objects of our invention will appear in the course of thespecification and be pointed out. in the claims, and with the fore:

going and related objects in view, our invention consists in the parts,improvements and combinations hereinafter set forth and claimed. I a ,7

While we have illustrated and shall describe a specific formaofconstruction, it is to be ,understoodqthat the same is for thepurposeofillustration only, and that our invention is not confined thereto, butis as broad as our claims, and that' numerous changes may be'madein theconstruction illustrated without departing from the principle thereof orsacrificing .the advantages of our invention In' he drawings forming apart of this specification and' wherein the same reference ,charactersare nsed to designate the same parts throughout, Figure 1 is a sideeleva- "tional view of one form of machine embody: ingoi rinvention;Fig. 21s a sectional detail viewv taken partly in section onthe line 22,Fig.1; Fig; 3 is a plan VIGW of the machine shown inflFig. 1 Fig. 4 is adetail cross secti'onal View taken on the line H, Fig. 3

'Reference numeral 1' is applied to the frame of the ,inaehina: whichmay take any convenient for-111,? but which is preferablyconstructediasgla closed vcasing for inclos- "ing the mdving'parts sofar as possible. A

main drive shaft 2 passes through the frame or casing l and is drivenfrom any convenient source of power, as for example by a belt applied tothe pulley 3, and this shaft 2 is further provided with one or more flyWheels l which may be rounded so as to be conveniently grasped by thehand of the operator, as upon starting the machine or moving it slowlyby hand if occasion should arise for such attention.

Our present invention is not directly concerned with the construction ofthe stitch forming mechanism and we may make use of any constructionforthis purpose. We have illustrated a form of stitch forming mechanism,commonly in use in various machines, such as fur sewing machines forinstance, and'which may conveniently be made use of for ourpurposes, andthis portion of the machine as illustrated may be described somewhatbriefly.

The needle bar 5 is actuated from the drive shaft 2 by means of aneccentric 6 on the shaft 2 working in a yoke 7 attached to the needlebar 5. The looper bar 8, which carries. or terminates in the looper 9,com

. prising the rounded heel extension 9 and the:

loop entering point 9*, is mounted on the shaft 10, which is rotatablyreceived in a frame 11, whichframe is pivoted at 12 .to a carriage 13,slidable in the machine frame, and which isreciprocated by an eccentric14 on the main drive shaft 2, working in a yoke ll which is securedtothe carriage 18. The frame 11 is moved up and down on its pivots 12;by a toggle system comprising a bellcra'nklever havingarms 15 and 16pivoted on the frame at 17, the arm 15 bein con nected to a link 18which has secured t ereto a. strap 20 for. the eccentric 19 also mountedion the drive shaft 2, and the opposite arm 16 of the bell-cranklever'is connected by the link 21 to the pivoted frame 11 and is pivotedthereto at 22. With this arrangement the link 21' and the arm 16 of thebell-crank lever comprise a toggle, which acts to raise and lower theframe 11, and the looper bar 8 borne thereby, twice in every revolutionof the drive shaft 2. The shaft 10 hearing the,

looper bar 8' is rocked in its hearings in the the shaft 10 v and havinga ball 24 fitting in the cam slot 25 in the rocking cam piece 26, whichis pivoted to theframe at 27, and is rocked on its pivot. from aneccentric 27 on the drive shaft 2 by means 'of a link 28 pivoperated-from an. eccentric 29 on the main shaft by means of the link 30provided with frame 11 by means of the arm23 secured to o 'ot'ed to thecampiece 26 at 28? and provided an eccentric strap fitting over theeccentric 29 on the drive shaft and the lever 31 pivoted' to the frameandto which said link is pivotally attached, link 32,-pivotallyconnected to the lever 31, and the step-by step, feed of the ordinarytype and having a spring attached thereto. This feed mechanism may beadjusted in any convenient and well known manner and operates to rotatethe shaft 29 intermittently through a small angle as each stitch isformed and. as will be readily understood.

The parts so far referred to being of any.

usual or desirable construction and operating in the usual manner to sewa chain stitch seam and to provide the necessary feed therefor need notbe further described. Coming now'to' the features of the ma chineillustrated which are original with us, H is a hat, S the sweat band orleather to be sewed therein and C the cord which is preferably sewed inwith the leather S but which may be omitted if desired.

The means for supporting the hat during the sewing operation comprlse aring for extending entirely around the hat, and

provided with a substantially cylindrical I is carried on a leg or legs40 which are free to swing on a pivot or pivots 41 and the entire hatcarrying frame-'may be adjusted vertically on the machine frame orcasing as by means of the. screw 42 which operates to raise or lower theframe 39 by turning the sub-frame 43, to which the legs 40 are directlypivoted, on its pivots '44. A spring 4-4? shown as a leaf spring, butwhich may be of any convenient form, serves to partially support theframe 39 and to prevent it from falling forward on the pivots -11 whenthe parts are separated as in removing a hat after it has beenseweda Thefeed shaft 29 heretofore referred to is provided at its upper end withthe feed wheel -15 which is formed with: a corrugated feeding surface onits lower side, having sub-. stantially the form of the frustum of aninverted cone, and which resting upon the rim of the hat H and incontact with the. underside thereof (turned upward in the sewingoperation) holds it firmly in place 'on the supporting ring 35 andoperates to advance the hat the necessary distance as each stitchiscompleted, in readiness for reu e t. ceivmg the next stitch. Means arealso provided for holding the hat and its supporting means firmly inplace in contact with the feed-wheel 45 during the sewing operation, andin the construction shown this means comprises'an idler or presser wheelto which is borne by the crooked armAT pivoted at 48 to an upstandingrod or post t9, Which is mounted in any suitable manner so asto bemovable substantially parallel to it-.

' selfth'us permitting the wheel 46 to be mo\ Jd straight toward 'andaway from the feed .*wheel 45. .As shown,'this substantially par-.

allel bodily movement of the rod or post 4-9 is secured by attaching tothe rod or post 49 a rigid horizontal, extension 50 and supporting it onlinks 51 and 52, pivoted i'espectively to the member 50 and to themachine frame. A spring 53 serves toretract the parts just described,thereby holding the post normally close -to the frame or casing 1 andsecuring a-firm contact of the of the hat, supporting the framework nwhich the hat rests and holding'the supporting member 35 and the hatitself resting thereon firmly against the feed wheel 45.

Other means than those described may, of course, be resorted to for. thepurposis named. A latch 53 of any convenient form is secured to anextension 54 onthe post 4 9 and holds the arm 47 and wheel 46 downfirmly in place. when the latter has been adjusted in position.

The means for controlling the tension, in order to successfully meet therequirements of sewing sweat bands into hats 'and to avoid tearing ofthe delicate material ofthe sweat bands, comprises a tension bar 55mounted for reciprocation in guides in the machine frame so as to moveparallel to and. at one Side of the needle bar 5. It is actuated by aneccentric 56 operating in a yoke 57 attached to the tension bar As shownclearly in Fig. 7 the eccentric 56 imparts to the tension bar. 55 athrowsomewhat more than half the throw of the needle bar 5 actuated by thecam 6.. The timing of the eccentric 56 is preferably so arranged as tobe slightly be-' hind the eccentric 6, but this timing is under. controland maybe varied to meet varying requirements, and, as shown, in orderthat the eccentric 56 may beaccurately positioned and adjusted so'as togive the best timing forthe tension control, it is adjustably secured tothe shaft 2 by means of a set screw 58.

In threading the machine thethread is passed from the spool 59 throughthe guide 60 and through openings 61 in lugs or projections 62 upon theface of the machine frame. Between the uFojections 62 it passes acrossthefront of the upwardly projecting portion 63,. of thetension bar 55and &

thence to its connections on the needle bar 5 and to the needle N.Theeifect ofthis arrangement 'is shown in the different posi-- tions ofthe parts illustrated in Fig. 9,.10, 11 and 12. In Fig. 9 the. needle Nis shown iirtlie position of its farthest advance wlth the looper inposition to take the loop about to be formed. Here the tension bar 55 isadvanced to its position of greatest advance, or nearly so, and thethread has been drawn up so that the coin-uleted stitch has been madesnug. In Fig. 10 the needle N has receded somewhat from the loop and thepoint 5) of the looper has entered the loop and has begun drawing outtheloop' for making the next stitch. The tension bar 55 has also recededsomewhat .leaving the thread slack for making the loop. In Fig. 11 theloop is completely formed and the needleh as advanced somewhat on itssubsequent advance stroke and is shown passing through the loop, and theslack provided by the tension bar 55 has been taken up in the formationof the loop. In Fig. 12 the loop has passed off the back 9 of the looper9 and the needle has advanced to complete the stitch, and the jointaction of the advance of the needle and the tension bar has drawn up thethread of the completed stitch so as to make the same properly snug andtight. As will be seen, the tightening of the thread all. takes place onthe inner side of the seam, that is to say, next to the ma-. chine frameor casing, and this tightening also takes place while the needle is inthe material being sewed and the needle thus holds the material'firm andprevents tearing; and the pull of the looper 9 on the thread to form theloop occurs while the thread is slack and plenty of loose thread isavailable for forming the' loop so that there is no tendency to tear thematerial by pullon the thread when the needle is disengaged therefrom.

The means for guiding thesweat band and the cord guide are shown clearlyin Fig. l. The needle guide bar 58 is secured to the arm 47, whichcarries the wheel 46 journaled on the journal 5!),by any convenientmeans asby the screw. 59 and is provided with a central-longitudinalslot 60 which the needle. enters and which guides the needle in itsmovement. This slot dividesthe upper poi tion of the needle guidebar 58into two parts, 61' and 62 the part 62 of the needle guide bar which isengaged first by the hat and sweat band is provid'edwith a projectinglip 63 for allording an upper edge guide to the sweat band'and isrecessedon the bottom at 6-l to guide the inner edgev of the sweat bandin its passage through the ma- I chine. The inner wall 65 of this recess64 is substantiallya continuation of the outer face 46 of the presserWheel 46, so that the 1" sweat band is held firmly in place and kept wea.

straight at and near its inner edge. The cord guide 66 is secured to asweat band guide carrying plate 67 which is also secured in place as bythe screw 59 to the arm 47. The sweat band guide carrying plate 67 isformed of thin spring material and is free to give somewhat to upwardpressure. It is provided with a downwardextension 68, which may be madein a separate piece, and an inner wall 69 which cooperates with the lip63 and the inner wall 65 of the recess 6% and the face 46 of the wheel46 to provide complete guiding means for the sweatband. The plate (3alsoextencs toward the machine frame at 70 to assist the feed wheel 15in guiding and holding down the hat during theosewing' is roundedupwardly so as to make it easy for the hat and sweat band to beintroduced and fed into the machine.

The operation of the machine described is as follows: The machine havingbeen stopped with the needle and looper in retracted position where bothare back of the edge of the feed wheel45, and are therefore out of theway, the latch 53 is turned so as to unlock the swinging arm l7 and thearm 4-7 is pulled forwardly so as to move the i presser wheel 46 awayfrom the feed wheel $5, the post 49 on which the arm 47 is pivotedmoving forward substantially parallel to itself upon its link supportand against the opposed pull of the spring 53 to permit theforwardbodily movement of the wheel 5&6 and-arm 47. The arm 4-7 is theirswungupwardly on its pivot 48, and, as a slight friction is provided at thispivoting point, thearm 4c? and the attached parts will re-' main tiltedupwardly and out of the way, as is clearlfshown in Fig. '5.- As thepresser wheel 46, when the partssare in working position, serves tosupport the frame 239 and the ring 35, on whieh the hat rests, againstthe feed wheel 45, when the presser wheel 4-6 has been moved upward andout of the way, the frame 39 will be free to he tilted outward on thepivot 41 by the operator applying pressure thereon against the action ofthe supporting spring l-l n The frame 39 being drawn forward by theoperator against the action of the spring H, the ,parts.are-entirelyseparated at the. sewing point. and a hat being first inverted mayreadily be 'placed'up'on the sup iorting ring 35 with the. crown-entering the opening with all the way around the ring, as will beunderstood. One end of the sweat band to be sewed in the hat is thenbrought into position with its edge substantially flush with the bentover surface of the hat at the bend on top of the ring 35, the end ofthe sweat band being opposite or substantially opposite the needle. Theframe 39 and ring 35 are then brought up. against the feed wheel whichrests upon the hat rim, contacting with the under surface thereof (whichis on 101), the hat having been inverted) near the bend where the sewingoperation is to take place, and the spring H supports it lightly in thisposition. hen the' parts have been arranged as described, the operatortemporarily holding the sweat band in position, swings the wheel +LG andarm 4-7 downward on the pivot t8 and holds the arm 47 forward againstthe tension of the spring 53 and then moves or pushes the same straightback, the post 49 moving substantially par allel to itself as has beendescribed, and the edge of the presser wheel 46 resting against theinside of the sweat band, pressing the sweat band, the hat and thesupporting ring 35 against thefeed .wheel 45 with sufiicient firmness toinsure a proper feeding action, and when the parts are .positioned inthis manner the latch 53 is looked over the arm l? to hold it down andretain it in the proper adjusted position. As the presser wheelJlG issupported so as to swing on its'pivot l8 and also so as to move straightin and out, the guide wall 69 may readily be brought into the properguiding relation to the sweat band and hat rim as the presser wheel 46and arm 47 and the guide members 68, 6,9 and carrying plate 67 bornethereby are depressed. and the parts brought into sewing position.Ifdesired, the operator can place the end of the sweat band a littleback of the sewing pointand after the parts have been positioned asabove described, can advance it slightly toward the sewing point so thatthe edge of the. sweat band will assume the proper position between theguiding surfaces, which consist of the edge 46 of the presser wheel andthe lower face (34 of the projecting lip 63 and the inner face (35 ofthe recess 64: and the wall 69 of the guide,

plate 68.

'The hat and sweat band having been positioned in the machine in themanner just described, and the cord which is preferably to be sewedbetween the sweat band and hat, having been'introduced in its properrelative position, being fed through the cord guide 66 provided for thatpurpose, the machine may be set into operation, the frame 39 havingfirst been properly adjusted in a vertical'direction by means of'thescrew 42 so that the needle will obtain the proper amount of bite on thematerial of the hat adjacent to the band to secure the sweat band firmlyin place and at the same time i not to penetrate through to the uppersurface of the hat. As the machine is operated the needle N will, passthrough a portion ofthe exposed edge of the hat at the bend and underthe cord C and through the upper edge of the sweat band S drawing thethread with it, and when the needle has reached its position of farthestadvance and has receded slightly so as to form a loop, thepoint 9? ofthe looper will enter the loop and draw it upward and to one side andbackward over the parts being sewed and then downward and to theopposite side of the needle, in order that the needle may pass beingsewed during the formation of, the

loop, as the looper has only to draw out a slack length of threadrequiring practically no pull. As the needle advances during thesubsequent stroke and while it is in contact.

with the parts being sewed, the joint action of the advancing needle andthe tension bar 55 results in pulling up the excess length of threadcontained in the loop, and brings the stitch when completed to theproper degree of snugness to secure the sweat band to the hat so that itis properly sewed in place and with the desired tightness of stitch andat the same time-without any tearing action. As already stated, the cam56 is capable of adjustment on the shaft 2 by means of the I set screw58, so that it may be set in such timing relation to the needle bar cam6 as that its operation will result in securing the effects which havebeen described.

It will be seen that as the machine is operated the feed wheel 45, inaddition to its feeding action in advancing the parts to be sewed thenecessary distance for the-formation of each stitch, also serves to holdthe hat rim down and to maintain it in contact with the downwardlytapering outer surface of the supporting ring 35, so that the seam willaccurately follow the turned over edge of the hat between the crown andrini. The

operator may place his left hand upon the hat where it rests on the ring35 somewhat in advance of the guide plate 67 and if, this is done andthe sweat-band held lightly up so that it will not dropbelow the guideplate 67 a substantially perfect seam will be readily secured. When theseam hasbeen sewed entirely around the hat the parts are disengaged inthemanner already described,

the thread and cord are cut off, and the operation which has beendescribed is re peated for each hat, although it will not be necessaryto adjust the device for height unless hats of different thicknesses areto be operated upon. The machine described is altogether positive in itsaction, the hat and sweat band and cord are firmly guided and supportedat the sewing point, and the disengagement is readily accomplished andis thoroughly complete, and plenty of room is provided to enable theeasy insertion and removal of hats and sweat bands, and with a machineas described the operation of sewing sweat bands into hats may beeffectively and quickly performed, the operator being able to turn outgood work rapidly and without any considerable exertion or closeattention.
